## Homework Statement

A charge q is released in crossed E and B fields: E is oriented along y axis; B is oriented about z axis

Derive the equation of motion of q

## Homework Equations

## The Attempt at a Solution

I'm not sure what equation I should use here, the only equation that I have which gives Force in terms of E and B is: F = q(E+v×B) , so I was thinking of using that, and set it equal to Newton's law F = m r'' , where r'' = {x'',y'',z''} , am I correct like that?
